Cyclic voltammetry showed that lead compounds of desulfurized lead paste could be reduced to metal lead. The effects of current density, electrolyte concentration, paste amount, and temperature on lead recovery ratio, energy consumption, electrolysis efficiency, and phase change in the whole electrolysis process were systematically investigated.
In this study, considering that the waste lead paste has poor electrical conductivity and low solubility in acidic solution because its main component is lead sulfate, the recovery of metallic lead from desulfurized lead paste by solid-phase electrolysis was initially proposed in ammonium sulfate solution.
Besides, the electrolyte after the completion of electrolysis could be reused for desulfurization of spent lead paste, and the XRD results showed the existence of desulfurization products, indicating that carbonate could be recycled in the recycling process of spent lead paste, saving resources, and reducing carbon emissions.
A green, efficient, and short route for recovering metal lead from spent lead-acid batteries has a great advantage in both environmental protection and sustainable development of lead industry. This paper developed a new scheme to recover metal lead by direct electrolysis in (NH 4) 2 SO 4 solution with desulfurized lead paste.
Because lead paste contains not only a large amount of PbSO 4, but only a small amount of PbO 2, PbO, Pb, and other minor impurities (Sb, Ba, Fe, Si, Cu) [6, 7]; therefore, lead recovery from the lead paste is the most critical part in the whole lead-acid battery recycling .
The influence of electrolyte concentration on the direct electrolysis of desulfurized lead paste was carried out in the range between 150 and 350 g/L with the current density of 200 Am −2, and other parameters the same as “ The Effect of Current Density ” section, as shown in Fig. 7.
